.RADIAN'I ELECTRIC HEATER Application filed August 29, 1928. Serial No.302,688.

' My invention relates to a radiant electric heater, and moreparticularly to one havingseveral separate units adapted to be connectedsingly, in series and in parallel to produce 'difierent degrees of heat.

An object of my invention is to provide a heater having a plurality ofwindings, with an arrangement of heater units whereby an even radiationof heat will be produced throughout the heater, irres ective of theparticular connections of t is individual units.

Another object of-my invention is to pro vide a new and novel supportfor electric heater units, whereby a p urality of units ma be carried onthe same support.

ther objects and advantages will be pointed out hereinafter asthe'description of my invention, taken in connection with theaccompanying drawings, proceeds. v

In the drawings I have shown, by way of illustration, an embodiment ofmy invention where- Fi 1 is a front elevation of a heater unit 2 suitale for mounting within a recess in the wall of a'room.

Fig. 2 is a side elevation, in section, of the heater shown in Fig. 1.

Fig. 3 is a perspective View of a portion of so the supporting means forthe heater units.

Fig. 4 is a modified form of a supporting I element.

In these drawings, 10 designates a housing member of sheet iron or thelike which is adapted to be recessed into the wall of a room.

Within the body 10 there is arranged a pair of parallel verticallyextending partitions 11 which are spaced from the side walls of themember 10, and arranged over the partitions 11 I provide a bafiie orcover 12 which acts to direct the radiated heat outwardly from thehousing 10. This baffle 12 is flared out toward the back of the housing10 at the point 14 and terminates out of contact therewith so that arestricted circulation of air will occur above the battle 12 and thusmore efiectively prevent overheating at the tag of thehousmg 10. It :isalso contempla to provide a suitable. ornamental illwork in across thefront of the housing for the purpose of enhancing its appearance andalso to prevent contact with the heater units.

.This grillwork forms no part of my invention and I have therefore, forthe purpose of clearness, not shown the same in the draw- 5 mgs. l

At a point near the bottom of the housing 10, I show a suitable switch15 which. is adapted to control the connections of the heater units andproduce various circuits which will vary the flow of current and thusproduce various degrees of heating, and extending horizontally above theswitch 15 and between the partitions 11 I provide a pair of tie rods 16upon which I thread a plurality of flat resistance unit supports 170These supports 17 are s aced uniformly upon the rods 16 by means 0insulating bushings 18, and are themselves made of a suitable insulatingmaterial. The resistance units are designated bythe numeral 19 and areshown as arranged in zig-za fashion over alternate supports 17 at the ons thereof. In Figure 2, I have shown an insulating connection strip 20upon which suitable terminals are provided for the ends of theresistance heater units 19 and switch leads 21.

This connection strip 20 is preferably mount-- ed below the heater unitsso that no leads will be exposed to view from the exterior of the heaterand the service leads 22 are inserted through a suitable opening in theside or back of the housing 10. 1

For a better understanding of the manner of supportin the individualheater units 19, attention is irected to Figure 3 of the drawings. Inorder to clearly illustrate, I have here shown an assembly wherein thebushing or spacers 18 are somewhat longer than those illustrated inFigure 1 and, as a result, the supports 17 arespaced further apart thanis usual. Normall the supports 17 will be s aced substantial y as shownin Figure 1.

rom an inspection of this figure of the drawings, it will be' seen thatthe supports 17 are each provided with a notch 23 at the ends thereofand that thesenotches 23 are arranged in o posite edges of the supportsso that when t esupports 17 are arranged alternat'ely in, reverse order,as shown, the

I arrangement of units.

notches 23 in the corresponding edges of the supports-17 will form aseries of hooks or notches alternately at the top and bottom of theheater into which the resistance units may be suspended in zi -zagfashion along both edges of the assem led group of sup-' ports 17. Asviewed in this figure of the drawings, one of the heater units 19 startsat the bottom and back of the left hand support 17 and then passes overthe notch 23 at the top and back of the next support 17, and so on, andthe other heater unit starts at the top and front of the left handsupport 17 and passes through the notch 23 in the bottom and front ofthe next member 17 and so on to theend of the heater. By thisarrangement, it will be seen that two distinct heater units may bemounted upon a single assembly of supports-17 and since the customarymanner of constructing three heat heater units involves only twoseparate resistance units which may be connected singly, in series, orin parallel, it will be seen that by this arrangement with the supports17 arranged edgewise to the front of the heater, I have provided, aseach of the units is extended completely across the front of the heater,a

mounting for the two units which will pro-' duce a uniform radiation ofheat from the face thereof. I

The modified form of the supports 17 shown in Figure 4 shows notchesarranged in both edges at the ends with the notches located nearer theends of the piece. With this type of support an assembly of same may bemade Wltl'lOUl) first considering the manner of winding the heater unitsas they can be started at either end or side, whereas with the type ofsupport shown in Figures 1, 2, and 3, some thought must be given to themanner of mounting and connection before the supports are assembled inorder to get a desired final This support is further shown as providedwith holes 2st spaced throughout its length. These holes 24 permit ofadditional circulation of air about the heater units and where thematerial is heavy or expensive, a reduction in weight or cost will alsobe effected.

From the above, it will be seen that I have produced in a radiantelectric heater of the multiple heat type, a support for the heaterunits which will permit of a uniform arrangement of the heater units andresult in a uniform radiation of heat across thefront of the heater,irrespective of the connections of the units, and while I haveshown forthe. urpose of explaining my inventiona preerred embodiment thereof, Idesire to have it understood thatI desire to cover by the appendedclaims all embodiments which fall within their spirit and scope.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. A resistance support for heater units comprising apair of parallel extending rods, and a plurality of flat insulatingmembers threaded in spaced relation'upon said rods having notchesarranged in opposite sides at the ends thereof, whereby two distinctresistance elements may be supported thereupon in spaced parallelplanes.

2. A resistance support for heater umts comprising a plurality of flatinsulating members arranged parallel in spaced relation and havingnotches arranged in opposite sides at the ends thereof, whereby twodistinct resistance elements ma be supported thereupon in spacedparallel planes out of electrical contact with each other, whereby moreuniform distribution of the resistance units suitablefor a three heatconnection may be obtained substantially as described.

3. A resistance unit for electric heaters comprising a plurality ofspaced parallel extending members having notches formed in their edgesat the ends thereof, and a pair of resistance units supported inparallel extending planes upon said members, said resistance units beinglaid along opposite edges of said members and engaging notches in eachalternate member at the corresponding ends thereof.

4. A resistance unit for electric heaters comprising a plurality of flatinsulating members arranged parallel in spaced relation, said membershaving notches arranged in opposite edges at the ends thereof, and apair of resistance units adapted to be connected to produce differentdegrees of heating laced in zigzag fashion along the opposite edges ofsaid supporting members and engaging the notches in alternate members asa means of support, whereby a uniform distribution of the heatingelements will be produced irrespective of the connections thereof.

5. An electric heater comprising a housing having, spaced walls, a pairof horizontally gaging alternate insulating members atthecorrespondingends, whereby each of said units will be evenly distributed across thefront of said heater.
